A Halogen-Free Flame Retardant Masterbatch (HFFR Masterbatch) is a concentrated additive, free of chlorine and bromine, mixed into plastics to make them fire-resistant, improving safety by slowing flames and reducing toxic smoke, while meeting stricter environmental rules (like RoHS) for electronics, construction, and other industries. It works by interfering with fire or forming a protective char layer, often using phosphorus or nitrogen-based compounds, ensuring plastics meet standards like UL94 without harmful emissions.
1. Chemical building materials: Halogen-Free Flame Retardant Masterbatch is widely used in the production of various chemical building materials, such as PVC sheets, plastic tiles, and building templates. These materials play a protective and decorative role in buildings and also need to have flame-retardant properties to improve building safety.
2. Foam Sheet: Used in the manufacture of polyethylene (PE) and polystyrene (EPS) foam sheets, which are commonly used in insulation, packaging materials, and thermal insulation. Halogen-free flame retardant masterbatch improves the flame retardant properties of foam boards and reduces the risk of fire.
3. Plastic Pipes: In the production of various plastic pipes (e.g. wire sheathing, water supply, drainage pipes, gas pipes), the addition of a non-halogenated flame retardant masterbatch can improve the fire resistance of the products to ensure that they will not be combustible in the event of a fire, and to reduce the speed of fire propagation.
4. Decorative materials: Used to produce indoor and outdoor decorative materials, such as wall panels, ceilings, floor tiles, window frames, and so on. These materials need to meet flame retardant standards to minimize the spread of fire and ensure the safety of people.
5. Fuel Tanks and Liquid Storage Containers: Halogen-free flame retardant masterbatch can be used in the production of plastic fuel tanks, chemical liquid storage tanks, and other containers that require high flame retardancy to prevent fires caused by external ignition sources or static electricity.
6. Electronic equipment and home appliances: In the production of electronic equipment (such as sockets, switches, connectors) and home appliance shells (such as televisions, refrigerators, and washing machines), the use of halogen-free flame retardant masterbatch can prevent electrical short-circuiting or overheating fires, and improve product safety.
7. Transportation: It is applied to the interior plastic parts of automobiles, trains, and airplanes, such as seats, instrument panels, interior panels, etc., to improve the fire resistance of the materials and ensure the safety of passengers.
